A Simple and Rapid LC-MS/MS Method for the Quantification of Nirmatrelvir/Ritonavir in Plasma of Patients with COVID-19

Figure 3

Dynamic variations of nirmatrelvir and ritonavir exposure levels in hemodialysis patients. The collecting points 1, 2, and 3 were the trough, 3 h and 12 h after administration, and the collecting points 4, 5, and 6 were time 0 h, 2 h, and 4 h in the dialysis process.
